Answer:
Explanation:
Rydberg's formula is used to describe the wavelengths of the spectral lines of chemical elements similar to hydrogen, that is, with only one electron being affected by the effective nuclear charge. In this formula we can find the rydberg constant, knowing the wavelength emitted in the transcision between two energy states, we can have a value of the constant.
Where it is the wavelength of the light emitted, R is the Rydberg constant, Z is the atomic number of the element and are the states where .
In this case we have Z=1 for hydrogen, solving for R:
This value is quite close to the theoretical value of the constant
Answer:
1.024 × 10⁸ m
Explanation:
The velocity v₀ of the orbit 8RE is v₀ = 8REω where ω = angular speed.
So, ω = v₀/8RE
For the orbit with radius R for it to maintain a circular orbit and velocity 2v₀, we have
2v₀ = Rω
substituting ω = v₀/8RE into the equation, we have
2v₀ = v₀R/8RE
dividing both sides by v₀, we have
2v₀/v₀ = R/8RE
2 = R/8RE
So, R = 2 × 8RE
R = 16RE
substituting RE = 6.4 × 10⁶ m
R = 16RE
= 16 × 6.4 × 10⁶ m
= 102.4 × 10⁶ m
= 1.024 × 10⁸ m
Answer:
The strength of magnetic field is 0.25 T
Explanation:
Time period sec
Mass of proton kg
Charge of proton C
Here proton moves in circular path
Velocity of proton is given by,
Put the value of velocity in above equation,
Now magnetic field is given by,
T
Therefore, the strength of magnetic field is 0.25 T
